What benefits can you get when buying joinery from Bertrand?


Bertrand is well-known by the highest quality of products. Components which we use are designed and produced in Germany. European windows is our specialization. With same components and constabtly developed production process we hear from our German clients that our windows are even better than in Germany. There is no difference to our disadvantage.

We use only German and Italian machines – but there is a one difference compared to our competitors. Practically whole production machinery is new, what provides higher quality for things like quality of welding of PVC corners or wood grinding. Luxury products like windows and doors from aluminum and wood are made by experienced handcrafters and carpenters with great support of automatized line for painting and square timber processing.
